Title: Improvements in or relating to methods of and apparatus for ventilating enclosures
IPC: F24F11/02
Filed: 1933-04-28
Abstract: 418,748. Controlling ventilation. CARRIER ENGINEERING CO., Ltd., and JONES, J. S., 24, Buckingham Gate, London. April 28, 1933, No. 12443. [Class 137.] A method of ventilating a number of enclosures 1, 2, each having an independent air control 6, 7 consists in employing a main air duct 5 of relatively large cross-section provided with a fan 8, the speed of which is varied according to the pressure in the duct 5, so that the amount of air circulated through any enclosure can be altered without affecting the amount passing through the other enclosures. The variations of pressure to the duct 5 are amplified by a bellows 13, rocker arm 14, leak port 16, and fluid connection 19 to two pressure switches 20, 21 which control a servo-motor 22 and reduction gear 25 rotating brushes 23 on the motor 9 driving the fan 8. Thus on increase of pressure in the duct 5, pressure switch 20 starts rotation of the servo-motor 22 in one direction to vary the fan speed switch 21 operating on reduction of pressure. The switches 20 and 21 operate at slightly different pressures to prevent " hunting " of the fan. The apparatus is applied to the extraction of air containing evaporated solvents from machines, as well as to ventilating rooms.

Abstract: 882,005. Making organo-metallic compounds, electrolytically. NALCO CHEMICAL CO. April 11, 1960 [May 6, 1959], No. 12771/60. Class 41. Organo-metallic compounds are made by electrolysis of a solution of a Grignard reagent in an anhydrous solvent using a sacrificial metal anode, and adding an organic halide of the same organic radical as the Grignard reagent, whereby there is formed a metal compound from the anode linked to hydrocarbon radicals. For example, a lead anode immersed in ethyl magnesium chloride dissolved in a solvent, e.g. diethyl or dibutyl glycol ether tri-hexylamine or pyridine, with added ethyl chloride forms lead tetraethyl which is separated from the electrolyte by distillation. Any magnesium metal formed at the inert cathode is reconverted to Grignard reagent by the ethyl chloride present. Voltage applied is 12 to 14V increasing to 24V, and at 35 to 60 C. or higher. Organo-metal compounds include methyl up to butyl and higher homologues; phenyl, and benzyl compounds of Pb, Ca, Zn, Hg, Mn, La, Te, Se, Tl, As and Bi. Magnesium halide also formed is removed to prevent resin formation, by adding dioxane or pyridine which forms complex insoluble substances. The process may be effected under pressure where volatile solvents are present.

Title: Improvements in or relating to temperature alarm devices
IPC: H02H5/04
Filed: 1943-08-09
Abstract: 568,934. Transformers. BRITISH ELECTRIC TRANSFORMER CO., Ltd., and WHISH, A. C. Aug. 9, 1943, No. 12834. [Class 38 (ii)] [Also in Groups XXI and XXXVII] A temperature alarm for a transformer or other electric apparatus comprises a temperature responsive device, a resistance element associated with it and adapted to be connected in the load circuit of the transformer and an iron-cored reactance shunted across the resistance element, the impedance of the reactance being high, as compared with that of the resistance element, over the normal working range of current, but relatively low if a substantial increase of current over the normal range occurs, due to magnetic saturation of the iron core of the reactance under those conditions. The resistance element is relieved by the shunt reactance of heavy overloads, and applies to the temperature responsive device an incremental temperature appropriate to the load current. The temperature responsive device may be of any indicating and/or recording kind, or one which will give a visible or audible warning and may comprise a bimetallic strip. It may be loaded so as to be released by fusion of. a retaining means to operate a switch. In all cases it is preferably arranged so as readily to be reset. In the form shown in Figs. 2, 3, the resistance element is in the form of a short strip of copper bent into circular form 10 and with the ends out-turned and secured to bent ends of two strips 1, 2, of the shape shown and connected in the output circuit of the transformer, and in-each phase of a multi-phase transformer. A sleeve 7 of insulating material passes through a hole in the strip 1 and is secured at its lower end by a screw 9 to a plug 8. The temperature responsive device comprises a cartridge 15 adapted to be removably secured in the sleeve 7 with a metal cup 20 containing fusible metal alloy 23 close to and within the part 10 of the resistance element. A screwed rod 16 is held at its lower end in the fusible alloy and is urged upwards by a spring 21. The reactance is formed by a copper bolt 24 extending between the plates 1, 2 with an insulating tube 25 between it and laminations 26 of magnetic steel, insulated from the strips 1, 2 by plates 27, 28. Fine adjustment of calibration of the temperature at which the device operates may be provided for by varying the extent of freedom of communication of oil between the space around the cup element 20 and the chamber which encloses the transformer. This may be done by providing in the sleeve, 7 near the cup element 20 one or more holes which may be closed by plugs. Instead of a fusible device, a bimetallic strip may be provided. In the form shown, upward movement of the rod 16 by fusion of the metal 23 in the cup 20, due to rise in current in the transformer output circuit, moves a ball 29 to close a circuit between two fingers 31. Alternatively, the rod 16 may turn a strip carried by a rod turning movement of which releases a hinged flap to give a visual warning.
